SPECIFICATION forming part of Letters Patent No. 285,953, dated October 2, 1883. Application filed May 9,1883. (No model.)

To aZZ whom it may concern:

Be it known that I, J AMES S. BARR, of WVheeling, in the county of Ohio and State of West Virginia, have invented a new and Improved Compression-Cock, of which the following is a full, clear, and exact description.

The invention will first be described in connection with the drawing and then pointed out in the claim.

Reference is to be had to the accompanying drawing, forming part of this specification, in which the figure is a sectional elevation of a stop-cock contrived according to my invention.

The valve a closes up under the partition 6 by the pressure of the water under it, and falls and vents the pipe cl, so that the water will drain out whenever the supply is shut off in mains, and will automatically rise and close the passage when the water is turned on, said valve having a stem, 6, that extends up into the socket f of the lower end of the handlestem g, that screws down in the cap h, to open the valve against the pressure of the water by the contact of the upper end of stem 6 with the bottom of the socket, but is screwed back to allow the valve to close by the pressure of the water. The stem 6 has a recess turned in it, below the upper end, for connecting the stem 9, by a set-screw, j, to prevent the stem 9 from being screwed out. This set-screw is so placed that it will limit the fall of the valve by the collar 76, which will lodge on it, and thus pre vent the valve from falling so low that it would fail to close by the pressure of the wa ter. The stem 9 is packed by the cap m, and

a plug, a, is located under the valve to open a hole for access to it. The set-screw j is applied when the cap h is screwed high up on the stem. 4

I am aware that it is not new to arrange a valve to close up against its seat under the pressure of the water, to drop by its gravity as soon as that pressure is removed, or to be opened in the water by a downward pressure upon the valve-stein; but

'WVhat I do claim as new and of my invention is The valve to, arranged to close upward against the seat b by the pressure of the water, and having a stem, 0, extending into the socket f of handle-stein 9, said stem 6 being recessed, and stem 9, provided with a set-serew, j, connecting them together and limiting the fall of the valve, substantially as described.
